X=9 and y=-3 if you need help comment back and i would love to help!
Once the rules of exponents are understood, you can begin solving more complicated expressions more easily. Recall that when you take a power to a power, you multiply the exponents, <span>(<span>xa</span>)b= <span>xa</span></span>·b.
<span>What happens when you raise an entire expression inside parentheses to a power? You can use the techniques you already know to simplify this expression.</span>
<span>(2a)4 = (2a)(2a)(2a)(2a) = </span><span>(2 • 2 • 2 • 2)(a • a • a • a) = (24)(a4) = 16a4</span>
<span>Notice that the exponent is applied to each factor of 2a. So, we can eliminate the middle steps.</span>
<span>(2a)4 = </span><span>(24)(a4), applying the 4 to each factor, 2 and a.</span>
<span>= 16a4</span>
<span>The product of two or more numbers raised to a power is equal to the product of each number raised to the same power.</span>
Answer:
any numbers that are multiples of 10, such as
10 and 20
40 and 60
50 and 80
Step-by-step explanation:
Because 5 is a factor of 10, all multiples of 10 will also be multiplies of 5, such as 10, 20, 30, 40, 50, 60, and so on.
Hello,
First we work out the equations:
x + y =62 will be the first equation.
2x= y +13 is the second equation.
We can first rewrite the second equation as 2x – y =13.
So we have:
x + y = 62
2x –y =13
KEEP IN MIND: With y being positive in one of the equations and negative in the other, we can combine the equations to quickly eliminate y and solve for x.
x + y = 62
+2x –y =13
3x = 75 divide both sides by 3 to get x.
x = 25
Now that we have x we can substitute the value for x, 25.
25 + y = 62 we can subtract 25 from both sides to get y.
y = 62- 25
y = 37
2(25) = 37 + 13
Therefore,
50 = 50
Have a amazing day.
